We'd love your feedback

We're getting close to finishing up the project. The code is stable and we're finishing up the documentation. If you have ANY feedback, we would love to hear it. What, if anything has been helpful? What hasn't been helpful? Anything
you are still confused about? If you have specific feedback about the documentation or the code, we still have time to make changes!

I just download your application and run it under emulator in VS2010. But when I try choose car picture (on CarDetailsPage click on PhotoButton, then select image) a exception always be thrown and application crash.

This leads to method SaveCarPhoto in CarDataStore.cs and some problem with WriteableBitmap type.
